Important: In the United States and some international markets,
the required ground bond is provided by the grounding conductor
in the cable and ac service conductors. If grounding is provided
through the grounding conductor and service conductors, no
additional grounding is required.
In environments where ac grounding conductors are not
available, a separate bonding conductor is required.
If a separate bonding conductor is required, ground the ac power
supply as follows:
1. Use a 2–hole lug to connect a No. 16 AWG ground wire to
the ground terminals on the front of the power supply. See
figure 6-10.

2. Connect the other end of the ground wire to the rack ground
bar. If the IDU chassis is not rack mounted, connect the
ground wire to a ground point such as a water pipe or
building steel.
